Broke what we will be when Iran gets nukes and the Arab states follow, jacking up oil permanently, and ending the very concept of Mutually Assured Destruction. Nuked American cities aren't cheap.
2) If Iran strike anyone it will be more likely Israel. Which Israel has Nukes. Rest assure they will fire back. Nevertheless, I don't think Iran is going to strike.
3) Most of the people in Iran do not like that dictator. Oh and he is controlled by the religious cleric too.
Sooo I doubt your situation will ever happen. I've been hearing this for a long time now since 2001. Still nothing... You remember the story of the boy who cried wolf?
